This is typically caused by an incorrect subnet mask setting for the IP address and default gateway IP addresses you are using. In the example above, a 24 bit subnet mask (represented by 255.255.255.0) was being used but the IP address and default gateway were on different segments. Upon trying apply these settings, the management card checks to ensure the gateway is routable and 0.0.0.0 is displayed because it is not in this scenario.

Resolution

Verify your IP address, subnet mask, and default gateway settings to ensure they are correct for your network setup. If incorrect, correct them and reapply the settings. A reboot (by logging off) may be required in order for this to apply properly afterwards.
